CAR ROOF.

Application filed October 14, 1924.

This invention relates in general to improvements in lireight car roofs and more particularly to improvements in the class oit car roofs usually designated as outside metal roots:7 whichjoutside metal root is inovably or flexibly positioned on the car so as to cover the wooden sheathing or inside wooden roof ot the car; and objects '1": the invention are the provision ot a metallic root capable of movement in harmony with. the motion ot the car without the necessity ot providing mullions to prevent the root itroln shifting; the provision ot anchors for such car roots which are not exposed to the elements and which are arranged to hold the sheets iti-oni upward movement and `also frointoo great longitudinal n'1ove ment; the provision ot a root which is lapahle oit simple manufacture at a rea sonablc cost and which can he readily applied on the car Without the necessity of specially skilled workmen and which when so applied will be water-tight and not require frequent repair and replacement; and such other objects and advantages ot the invention as are found to obtain in the structure hereinafter' set forth and claimed ln the accompanying drawings forming a part of this specification, and showing7 ior purposes of exeunpliiication, a preferred torni and lnauner in which the :invention may be embodied and practiced, but without limiting the claimed invention specifically to such illustrative instance or instances:

On the drawing 10 indicates the wooden side plates that extend longitudinally of the car and 11 is the inside wooden root" sheathing which terminates at the eaves flushv with the outer face of the side plates. 12 is the .side sheathing of the car, the upper edge ot which is flush with the upper surface of the wooden root sheathing at the eaves. At each eaves edge the root sheathing is gained out at 13 to receive a metal lashing 14 whose inner edge terminates in an upwardly pro-- jecting open return bent hook 15 whose up- Vier surtace is below the plane ot the top ol the gained root sheathing and this flashing is flanged at its other end, which lange 16 depends over the eaves edge of the root and secured thereto. Roof sheets 17 are disposed on opposite sides et' the ridge, said root sheets having inverted Usshaped ridge flanges 18 lapped one over the other and side flanges 19, said side Hanges 19 consisting of an upwardly extending inwardly inclined portion Q0 termi nating in. a downwardly extending portion 21 spaced trom seid portion Q0 and also spaced fromV the main body of the roof sheet 22.

At the caves edge the root sheets are bent under at 23 and then inwardly at 24; and the inner edge of the portion 24 is bent up wardlyy at 25 to form a return bent hook 26 spaced from the portion 24. These portions 23. QAf, 25 and 26 form a lateral stitl'ening roll for the eaves edge of the roof sheets. and within the roll there is provided a locking strip Q7 which extends outwardly from each side ot the root' sheet at Q8 and the extensions Q8 are bent upwardly at 29. It desired, these locking strips need not extend throughout the length of thelateral 'stiiening roll, but may consist of short pieces crimped or otherwise secured to only the side edges of the root sheets. Root anchors are pro` vided, in the present instance, secured on the flashing 14 at the eaves edge of the car` one between the sides of each two adjacent roof sheets. These anchors consist of a top web 31 having depending and inwardly inclinedsides 32 spaced from each other to provide a space 33 and said sides terminate in outwardly extending flanges 34 spaced from each other, which flanges 34 may be considered the main body of the anchor as they support the sides 32 and web 3l and are secured to thc roof sheathing bynieans passing through the apertures 35 therein. Ono end of each of said flangesv 34 is bent downwardly over the edge of the roof forining depending flanges 36 which are secured there to the side of the car by nails or other suitable ineens 37. The lower ends of the .sides B2 are cut away to provide slots 88 through which the extensions 2S pass and the upwardly bent por ion Q9 of the lo ng strips are thereby loosely confined. withi' the space 33 so that the roof sheets inay partalre of proper movement and yet be effectively held down on the roof shezfithing` and prevented froin shi fting.

A 4plate 39 rigidly secured as by welding 39 to the top surface of said flanges 34 of said anchor, said plate covering the space between the flanges 34 beneath the slots 38 and said plate also has at its outer end a tongue 40 which may be bent up to secure a side seam cap in place. Side scam caps 4l extend from ridge to caves, said caps being of substantially tubular forni and having curved sides 42 inwardly turned at their lower ends and terminating in upwardly eX- tendiing flanges 43 spaced from each other and from the sides 42 and when assembled on. a roof, said flanges 43are arranged in the spaces provided between the portions 2() and 2l of the side flanges 19 of the roof sheets. the anchors that are secured at the eaves between the sidesof adjacent roof sheets, and as they are not connected with the anchors, the anchors may be positioned on the roof sheathing before the seani caps are au plied and the anchors may and do hold the roof sheets down independently of' the seein caps. The eaves ends of the side seam caps .are closed by bending the top and 'sides of ythe sealn cap one over the other as shown in F 5. After the seain caps are arranged inplace on the roof, the tongues 40 are bent up over the end 43 of the caps which holds the cap in position The ridge ends of the roof sheets are capped by inverted U-shaped caps 44 having outwardly extending flanges `45 arranged over the ridge edges of adjacent and to the wooden roof sheathing, as shown in Fig. 9, by a bolt 48 which passes through These seani caps, as shown, enclose the usual running board saddle 49, inverted U-shaped ridge cap 44, lapped ridge ends 4G of the side searn caps 4l, wooden roof sheathing ll and longitudinally extending ridge pole 51.

The invention is hereinabove set forth as cinbodied in a particular forni of construction but inay be variously embodied within underbent portion spaced from the niain body of the sheet, a locking strip positioned in the space defined by said return underbent portion of the sheet and projecting upwardly between the edges of adjacent sheets, anchors secured. at the eaves edgesV of lheroof between the sides of adjacent roof sheets, said anchors having upwardly bent portions providing a space, said last named portions being connected by a top web and cut away at their lower ends to provide slots through which the locking strips cxtcnd, the upwardly bent portions of the said strips terminating in the space provided by the bent portions of the anchors, seam caps enclosing the adjacent side flanges and adjacent roof sheets and the anchor therebetween, and a flashing and'holding piece secured tothe anchors and having a portion adapted to prevent outward movement of the seain caps.v
